Global warming and humidity
Name: James E Backstrom
How does global warming effect the percent humidity in a given region?
I know of no regional predictions of relative humidity under global warming
assumptions. Global climate models have very limited abilities to predict
local or regional weather conditions.
For a general overview, see "Science Digest", October 1985, which features an
article on "Will We Ever Control the Weather." For more technical information
on the state of the art, see:
"Development of a Second-Generation Regional Climate Model" pages 2794 in the
Monthly Weather Review, October 1993.
"The Global Precipitation Climatology Project: First Algorithm Inter-
Comparison Project" page 401 in Bulletin of the American Meteorological
Society, March 1994
I think that it is important to understand that global warming will likely not
cause all areas of the globe to warm up. The change in temperature will cause
the weather patterns to change, and will likely cause a change in the pattern
of flow of the oceans. These changes will affect different parts of the globe
differently, so that some parts of the world may in fact become colder.
Humidity should also be affected differently in various areas.
